So the #define IGN should go as well...
Actually, I don't really understand this code part:
* What is the purpose of the lookup table for the switch rather than 
just switching on a few special control characters?
* What is the idea of (randomly?) assigning ERR to some control 
characters and NOR to others?
* How does the case NOR *work* actually? The characters *do* print out 
although according to the code only a replacement char U+2592 is 
written. Am I half-awake?

Maybe after clarifying this, the whole snipplet should be cleaned up a 
little bit.
